MATERIAL FOR BUILDING CONSTRUCTION.

Application led February 20. 1920.

To all whom it may (fonce/'u Be it known that l. llENnY lV. lVurr, a citizen of the United States, and resident of New Orleans, parish of (')rl-eans, and State of Louisiana, have invented certain new and useful Improvements in Material for Building Construction, of which the following 1s a specification, and which are illustrated 1n theaccompanying drawings, forming a part thereof.

The invention relates to buildings and has for an object the provision of a forni of construction that shall be simple, durable. warm, cool, cheap and which may be constructed with a minimum of skilled labor.

the invention is the provision of a form of material that may be used in such construction.

An illustrative embodiment of the invention is show n in the accompanying drawing in Which- Figure l is a perspective view of a portion of 4a building partially completed, and partly broken away to show the construction, and

Fig. 2 is a detail longitudinal section of a piece of material embodying the improvement in building material. o

A building constructed according to the. present invention, as shown. comprises as to Walls, merely the studding or other frame members, and sheets of material. in the nature of artificial lumber, secured directly thereto and providing all necessary elements for warmth, Weather resistance and outside finish of a pleasing appearance. The same structure may also provide the roof if de sired but since the construction thereof will be obvious it is not considered necessary to illustrate the same The material 4made according to the in vention comprises, as a ma'or element, a layer, as 10, of dry waste fi rous material suchjas straw, dried rasses of any character, dry leaves, Wee s or any other Waste material that may be available and which when treated as described, is capable of being formed into .a layer of sponge-like nature. To provide the material of the invention the waste material is treated with a waterproofin substance which is capable of the e ements of the fibrous material to adhere to each other at their points of contact without filling the interspaces in the mass.

The Waterproofing material at present Specification of Letters Patent.

Serial No. 360.092.

prefered for this purpose is asphalt of not too soft a composition. lf such an asphalt be applied hot, or in fiuid condition by reason of containing a cut-back as benzohthe individual fibers or elements of the waste material will be saturated thus rendering the material of these fibers or elements waterproof. To attain the result contemplated hy the present invention this water proofing treatment is carried out in such a manner as to leave no surplus waterproofing material in the mass. only enough being applied to saturate the individual fibers or cle ments and leave the thinnest possible coating on their surfaces. lVhile the wateu proofing material is still soft and adhesive the material is preferably compressed to a sufficient degree to cause the points of contact of the elements with each other to adhere, but not suflicient to close the cells of the mass.

The compression of the cellular mass is preferably produced in the operation of applying surfacing layers to the mass. shown, a back layer. as-11, is provided. formed of felt saturated with asphalt or other waterproofing material. fabric or paper which layer may bc coated with an adhesive substance 12. preferably asphalt. of the Same nature used in treatment of the fibrous layer 10, for the purpose of causing it to adhere to the cellular layer 10. Thilo the backin layer 11 is preferably throughly Vvvaterproo yet this quality is not essential since it is not directly exposed to the ele ments.

As a facing for the cellular layer 10. there is shown a layer 13 preferably felt saturated with asphalt and having` a layer or coatingr of asphalt 14 similar to layer 12 applied thereto to cause adherence of the cellular layer thereto. Preferably the layer 13 is faced by a coating of asphalt 15 having grit, sand. shell, or other non-adhesive refractory material. as 16. embedded therein to conceal and protect asphalt and to provide a pleas ingappearauce.

o enable the material described to serve without suport other than the frame members of the uilding, the material is so assembled as to be rigid and is formed into flat sheets of a size convenient for handling. Rigidity of the material is furnished by the layer 10 which. for this purpose. is made very much thicker than layer 11 or than combined layers 13. 14, 15. This is feasible because of its cheapness and the thickening of this layer secures the function of heat insulation due to its cellular nature in addition to rigidity. The sheets of material formed as described owe some of their rigidity to an action of the parts of the nature of a truss actioii,sii1ce the surface layers act as tension members and the layer 10 as a body cross connected lattice work.

Having provided sheets of the nature described, a wall may be very readil constructed shown, by erecting studding, as 1T, so spaced that the edges of the sheets may meet on certain of the studs, and the sheets may be nailed directly thereto. To make the joints Weather proof and invisible, the edges of the sheets may be coated with Huid asphalt and may be pressed together. The raw asphalt exposed at the joint may be concealed by taklng loose ma terial of the nature utilized for layer 16 and pressing it against the joint as by a trowel. The nall heads may be covered by asphalt and grit may be applied thereto at the same time as to the joint. y

lf preferred` the joints may be covered as by a hatten 18 and corner boards 19. When this practice is followed, half timbered effects may be readily secured by other pieces 2l)` 21, placed between kthe battens.

A building embodying the present invention may be constructed in a minimum time with very little skilled labor, and Will be durable, Warm in Winter and cool in summer and its exterior may be given a pleasing appearance chosen from a wide variety of possibilities.

Minor changes may be made in the physi-I cal embodiment of the invention without departing fromlits spirit.

I claim as my invention:

1. A sheet material for the exterior of buildings comprising, in combination, a layer of waste material, the individual elements of which are Saturated and thinly coated with waterproofing material, said elements adhering to each other at their points of contact to form a cellular mass, and a Waterproof facing layer adhering to said first named layer.

2. A sheet material for the exterior of buildings comprisin in combination, a major layer of waste #brons material, the indivdual elements of which are saturated and thinly coated with bituminous material, said elements adhering at their points of contact in the mass to form a cellular mass, a waterproof facing layer adhering to and closing the cells of said layer at one surface thereof and a backing layer of sheet material adhering to and closing the cells of said layer at the other surface.

3. A sheet material for building construction comprising, i'n combination, a major layer of Waste fibrous material having its individual elements thinl y.coated Wlth as phalt and adhering at t eir points of contact to provide a rigidity-giving, heat-insulating cellular mass, a b'ackin layer ad hering to and closing the cells o said layer at one surface, a waterproof-.facing layer adhering to and closing theVA cells of said layer at its other surface and a layer of weather proof finishing material adhering to said surface layer.
